[2036] Integrate valgrind into our test suite

* Supply --enable-valgrind to configure to run tests (make check)
  under valgrind

* Use two classes of suppressions files:
 + src/valgrind-suppressions for permanent suppressions that we
   never want to re-consider again
 + src/valgrind-suppressions.revisit for temporary suppressions
  (such as issues in testcases) that are not a priority to fix,
  but we'd like to fix them sometime
